  • A modelling study of the bilobate nucleus of comet 67P/Churyumov–Gerasimenko reveals that it has spun much faster in the past, but that its chaotically changing spin rate has so far prevented it from splitting; eventually the two lobes will separate, but they will be unable to escape each other and will ultimately merge again—a situation that seems to be common among cometary nuclei.

  • Analysis of a kilometre-sized, near-Earth asteroid shows that forces weaker than the weight of a penny can keep it from falling apart. This has implications for understanding the evolution of the Solar System. See Letter p.174

  • The impact of the DART spacecraft on the asteroid Dimorphos is reported and reconstructed, demonstrating that kinetic impactor technology is a viable technique to potentially defend Earth from asteroids.

  • Double Asteroid Redirection Test (DART) mission’s impact on asteroid Dimorphos has led to various impact related features. Here, the authors show that those features result naturally from the dynamical interaction of the ejecta with the binary system and solar radiation pressure.
